I have a 641 that I use to sickle mow hay with. The sickle mower is 3PH mounted. After working a while and the oil is all hot the 3PH won't always lift the mower. Sometimes I can get it to lift by working the quadrant back and forth and other time I partially flip the draft lever under the seat to get it to lift. Without the mower on is always works. So do I have an internal leak?, relief valve problem? I do have a lift kit but never installed it. I can't find good instructions on how to do that.
